When a woman is annoyed at a man.
A woman who has "man rage" will consider all men to be annoying, she will have lost faith in man kind.

For example, a woman with man rage will have little patience with a man and will think of them all to be arrogant, eco-centric and impolite. She will feel like real gentle men are now an endangered (if not extincted) species.
